ED OUARD A. THIERY, OF NEWARK, NEW JER sEY.

BRACELET.

SPECIFICATION forming part of Letters Patent No. 244,687, dated July 19,1881.

- Application filed June 17,1881. (Model.) 7

To all whom it may concern 7 Be it known that I, EDOUARD A.THIERY, acitizen of the Republic of France, residing at Newark, in the county ofEssex and State of New Jersey, have invented certain new and usefulImprovements in Bracelets, of which the following is a specification. I

My invention relates to certain improvements in the joint which unitesthe members of a two-part bracelet, and is specially appli cable to theclass of bracelets known in the trade as bangles, although it may beapplied to any two-part bracelet.

In the accompanying drawings, forming a part. of this specification, andin which like letters of reference indicate corresponding parts in allthe views, Figure 1 is a side ele-' ment in a closed position. Fig. 2 isa side elevation, showingthe same opened. Fig. 31s a vertical section ofa portion of a bracelet adjacent to the hinged joint, to show moreclearly the construction of the parts.

A B represent the two parts of the bracelet, which may be left open atthe top, and provided with any suitable ornaments representing the classof articles known as bangles,

' or theymay be provided with suitable clasps,

so that when closed they will form a continuous band, as in the ordinaryform of bracelet. The two parts are hinged or pivoted, as at a, by anypreferred form of articulation. The structure of the partsjust'mentioned is well known, and any. further detailed descriptionthereof would be superfluous.

I will now proceed to describe my improvements.

The two sections A and B may be either solid or tubular; but in casethey are made solid the section A is slotted and provided at its lowerend with a chamber for the reception of the coiled spring 6, t hepurpose of which will presently appear. In the chamber at the lower endof partA is inserted acoiled spring, 0. When,the bracelet is made hollowor tubular a small. diaphragm, f, is securedin the inside of part A asuitable distance from the hinge, and against which the upper end of thecoiled spring 0 rests.

Over the lower end of section A, and adapted to slide thereon, is asleeve, 0. This sleeve is provided with'a short stud, d, which projectsthrough a slot cut in the end of part A,

and this stud rests against the lower end of the coiled spring 6 in thechamber. The sec tion B may be provided with an annular projection orflange, b, which acts as a stop for the sleeve; but this stop is 'notessential, and may be dispensed with, if desired. Iprefer to use it,however, especially when the opposite end of the sleeve is provided witha like rim or flange, as it gives'the bracelet a more uniform appearanceand relieves the spring from undue tension. the drawings, which entirelysurrounds and covers the joint, is the preferred form of construction,as it produces a more, pleasing effeet and excludes all dust and dirtfrom the spring and its chamber; but I sometimes make the sleeve inskeleton form, or use a simple segmental bar, in each instance providedwith thestud f, adapted to act against the end of the spring, in thesame manner as when the solid sleeve 0 is used.

- The operation of the device is obvious. By sliding the sleeve alongthe lower end of part A until it has passed the joint in theguiding-slot, stud f compresses thespring, and the parts A B may beswung open, as in Fig. 2.

It is then in a position to be applied to the wrist of the wearer. Bysimply closing the free ends of the parts the sleeve 0 is automaticallyforced over the joint by means of a spring, half of the sleeveencircling each of the ends of the two parts, which are locked in aclosed position and cannot be opened without pushing back the sleeve.

Having thus fully described my invention, what I claim is- 1. A braceletconsisting of two sections hinged together, and provided with a sleeveor slide which is adapted automatically to cover the hinge-joint andlock the bracelet, substantially as specified.

2. The combination of part A, slotted as described, provided-with achamber at its lower end and inclosing a coiled spring, the part B,hinged thereto, and the sleeve 0, carrying the stud d, substantially asvspecified.

' 3. The combination of part A, having a guiding-slot at its lower end,and a chamber inclosing a spiral spring, part B, having stop I), andsleeve 0, provided with a stud, 12, substantially as specified.
